A. Lachkar et al., METALLIZATION OF POLYTHIOPHENES .1. INTERACTION OF VAPOR-DEPOSITED CU, AG AND AU WITH POLY(3-HEXYLTHIOPHENE) (P3HT), Synthetic metals, 66(3), 1994, pp. 209-215
We have studied the chemical structure and the nature of the reaction
at the interfaces between a semiconducting conjugated polymer, poly(3-
hexylthiophene) (P3HT), and the three coinage metals: Cu, Ag and Au. T
he initial stages of interface formation were followed, with the type
and extent of chemical reaction being determined by XPS. It is found t
hat both Cu and Ag react exclusively at the S atom of the P3HT while A
u does not appear to react at all.
